Exam CV0-003 topic 1 question 131 discussion

Explanation: Since the issue is identified as disk-related due to a lack of IOPS on spinning disk storage, the most effective way to improve performance is to move the virtual machine to flash storage (SSD/NVMe). Flash storage has significantly higher IOPS and lower latency, which will enhance database performance. Testing after migration will confirm if disk performance was indeed the bottleneck.

sys admins BELIEVES. He must test it to be sure

The key word is NEXT.

This looks a troubleshooting question in disguise. C is going backward in the troubleshooting scheme. B would be testing the theory that the admin has formulated. I would select B.

Classic CompTIA poorly written question. Verifying that it's not a config issue first would potentially avoid unnecessary expenses involved with swapping over to SSDs. But who knows what they're going for here. Both B & C could be argued.

B. Move the virtual machine to flash storage and test again. Explanation: If a performance issue has been identified as disk related and the cause is determined to be a lack of IOPS on the existing spinning disk storage, the next step to resolve the issue should be to move the virtual machine to flash storage and test again. Flash storage is known to have a much higher IOPS capacity than spinning disk storage, which should help to resolve the performance issue. Upgrading the virtual database server or checking if other machines on the same storage are having issues may not necessarily resolve the disk-related performance issue. Documenting the findings and placing them in a shared knowledge base is important, but it should not be the next step in resolving the issue.

C. He was diagnosing an issue of lack of IOPS from the server. He needs to check the other VMs running on that disk to rule out that it's not a faulty disk.

Answer C would help to see if it's a bad config/bad disk issue, but it won't solve the issue right away, the answer that would solve the issue if it's a IOPS problem is answer B

He has established the theory. Now he needs to test it.

sorry could be a bad config on the one device which is why you should check other machines

Could be a bad disk which is why you should check other machines

B. Move the virtual machine to flash storage and test again. The administrator has identified that the issue is disk-related and that the cause is a lack of IOPS on the existing spinning disk storage. Moving the virtual machine to flash storage would improve the IOPS and would help to resolve the performance issue. The other options would not directly resolve the issue. It is always good to document the findings and place them in a shared knowledge base, but this should be done after resolving the issue.
